Lefranc Bourgeois White Courtrai Drier is a mild traditional medium that accelerates complete curing, rather than just superficial drying. It is an essential additive to control the drying rate of pigments.

Courtrai drier makes the oil to demand more oxygen and therefore accelerates the hardening of the layers of paint. With age, the paint layers will have the same hardness and will be more uniform. The pale colour does not alter light colours.

Recommended use: 2-3 drops per pea-sized amount of paint.
